-- Audit logging for SQLite (libsql/better-sqlite3).
--
-- Postgres used a generic trigger function + a per-request session variable
-- (set_config) to attribute audit rows. SQLite has neither, so we emulate it:
--   * audit_ctx holds the current user id for the active connection (set by the
--     app via setAuditContext() before each mutation).
--   * Per-table AFTER INSERT/UPDATE/DELETE triggers write audit_log rows,
--     reading the actor from audit_ctx.
--
-- NOTE: audit_ctx is connection-global. Attribution is correct when mutations
-- run serially per connection (the better-sqlite3 case); under heavy
-- interleaved concurrency the actor could be misattributed.
